going out

I'm a nurse and I work every other weekend. Every weekend I'm off my husband goes out Thursday night until Saturday night. Doesn't get home till 1-2. It's either to the bar or friends house. I'm at my ends point. I could understand one night but it seems every day I work he is out with friends. How would you feel if you were in my position? Also he only works part time. Has a huge job lined up but he think he should get it in (partying) since when it comes through he will have to stop. 
Edit: when I talk to him he says he has nothing else to do since I go to bed early and work the next morning and he is always good.
